feat(ocurl): simpler, cleaner backend implementation 
we now only have a single representation of a batch, with its own
internal state to handle timeouts. It handles its own locking, and there
are no callbacks anymore.

config: more comments; make Config.t private 
forcing users to use `Config.make` to build a new config means we can
add fields without breaking existing code.

feat(otel): Metrics_callbacks module 
this module allows the user's programs and libraries to register
some callbacks that will be regularly called to produce metrics.

fix: yet another fix for emitting GC metrics 
now, the frontend (Opentelemetry) is responsible for signalling the
backend when to emit GC stats; but the backend just samples GC metrics
on the next `tick()` and pushes them in the next batch. This saves us
from having to worry about re-entrancy and GC metrics being emitted
during the emission of something else.

feat(collector): move GC metrics logic to the collector 
this helps avoiding reentrancy issue, where the collector allocates,
triggers the GC metrics alarm, which tries to push new metrics in the
middle of a batch (currently leading to a potential deadlock).
